A stopper mechanism is not provided on a turning unit but is provided on a horizontal portion and a mirror assembly. Therefore, the turning unit can be used for a left outer mirror and a right outer mirror. The mirror assembly is provided with a projection of the stopper mechanism, and a base is provided with an arc groove of the stopper mechanism. Therefore, it is unnecessary to split the base into two pieces at the time of molding using a metal mold, and the base can be formed using the metal mold in a usual manner and thus, the cost of manufacturing becomes inexpensive.
